According to The Arizona Republic, the 15-year-old student emailed a letter to more than 5,000 school administrators and lawmakers in early December, demanding better legislation against discrimination.
Caleb's letters push for new school policies that will specifically prohibit gay harassment by students, teachers and administrators. If these policies are not enacted, the Gays and Lesbians United Against Discrimination founder says the schools will face "legal ramifications."
"This is more not to threaten a lawsuit but to put resources out there," Caleb said. "But if they don't want to cooperate, there's going to be consequences."
Last year, the Surprise, Ariz. teen enlisted the help of the American Civil Liberties Union to get his school district to change its anti-bullying policy, saying that it should be amended to include sexual orientation and gender identity in its language.
Caleb said he was a victim of bullying and harassment, and even received death threats from other students. He felt that his school could have done more to stop it.
